Kyrgios in fiery exit at Indian Wells

Nick Kyrgios has lost his opening match at the Indian Wells tennis tournament in California, swearing repeatedly in the second set of the straight-sets loss.

Playing for the first time since controversially missing Australia's Davis Cup tie against the USA at Kooyong last weekend through illness, Kyrgios was beaten by Spain's Albert Ramos-Vinolas 7-6 (7-4) 7-5 on Sunday morning AEDT.

Losing 3-2 in the second set, Kyrgios was heard on the television broadcast pleading emotionally with the chair umpire.

"What the f**k just happened?" the Australian said.

"Please Nick, stop using `F' words," the chair umpire responded.

"I didn't say anything mate," Kyrgios was heard saying.

"I don't wanna play anymore, this is bulls**t," Kyrgios went on to add.

During the opening set, Kyrgios was given a warning from the chair umpire for smashing a ball high into the stands after hitting a return long on the first point of the tie-breaker.

Kyrgios's fiery exit from Indian Wells is the latest episode in a controversial period for the world No.27, who upset compatriot Bernard Tomic by missing Australia's Davis Cup loss against the USA with illness.
